Definitions

  • the present invention relates to prefabricating cables.
  • the present invention relates to the contacting of cables comprising light metal litz wires, for example aluminum litz wires.
  • the invention is also transferable to other litz wire materials, for example magnesium and copper litz wires or to litz wires made from alloys composed of one or a plurality of the materials referred to previously or other suitable materials.
  • Such cables are used mainly in motor vehicle construction to supply electrical consumers with electric power.
  • Such cables are also used for grounding electrical systems.
  • the present invention also relates to a prefabricated cable.
  • DE 10 2008 031 588 A1 proposes to bond light metal litz wires to a contact element using an ultrasonic welding process wherein first of all a sleeve is cold-welded to the exposed ends of the light metal litz wire using the ultrasonic welding process. This sleeve is then used for contacting with the contact element.
  • the ultrasonic welding process takes between 500 and 1,500 ms. Alternatively known soft or hard soldering processes actually take several seconds.
  • WO 2008/104668 A1 An alternative method is disclosed in WO 2008/104668 A1.
  • This method uses a magnetic pulse welding process by means of which the sleeve of a cable lug is cold-welded to the exposed litz wire of a cable as the contact element.
  • the sleeve by analogy with known mechanical crimping or caulking, is pressed onto the litz wire from the outside with extreme acceleration using the magnetic pulse welding process in order to create the contact with said litz wire.
  • This method has the disadvantage that the effect of the magnetic pulse decreases towards the center of the litz wire. As a result, cold welding no longer takes place between the individual wires situated in the center which means that both the reliability of the mechanical joint between the contact element and the litz wire and also the joint's electrical conductivity is reduced.
  • the object of the present invention is to create a method for prefabricating cables which with a comparatively short process duration guarantees more reliable contacting, by comparison with WO 2008/104668, of the contacting element with the litz-wire conductor of the cable even when using light metal litz wires.
  • the present invention relates to the creation of a prefabricated cable which can be manufactured in a short process duration and therefore inexpensively and which enables more reliable contacting of contact elements with the litz-wire conductor of the cable even when using light metal as the conductor material.
  • the present invention is based on the concept of ensuring, by providing at least one abutment inside the litz-wire conductor, that the mechanical pulse is also transferred in the optimum manner to the inner individual wires and therefore to prevent a reduction in the quality of the electrical and mechanical contact towards the center.
  • the present invention proposes a method for prefabricating cables.
  • Prefabricating of cables in this context is to be understood as the production of ready-to-install cables, cable bunches or whole cable harnesses together with contact elements. Any connectors and contacts are included as contact elements within the meaning of the present invention.
  • Cable lugs and round pins for high-voltage applications are mentioned purely by way of example.
  • the cable to be prefabricated is typically a single-core cable with a litz-wire conductor.
  • the cable may also, however, have a plurality of cores, i.e. litz-wire conductors electrically insulated from one another and additionally a shield such as is necessary, for example, for high-voltage applications.
  • a litz-wire conductor is composed of a plurality of individual wires.
  • a plurality of litz-wire conductors are also stranded together for reasons of symmetry which therefore results in turn in an approximately round cross-section of the conductor.
  • the wires of a litz wire are preferably formed from a light metal or a light metal alloy, such as magnesium or aluminum or alloys thereof. Pure aluminum is especially preferable for use here due to its cost and weight advantage.
  • the method according to the invention includes the introduction of a least one preferably elongate, in particular pin-shaped abutment on the end of a wire in a preferred embodiment into the center of the exposed litz-wire conductor, i.e. between the individual wires of the litz-wire conductor.
  • a partial length of the cable or the wire is stripped, preferably in a previous work step, in order to expose the litz wire.
  • Introduction of the abutment may be carried out in such a way that first of all the individual wires of the litz-wire conductor are pushed apart in a separate step to create an appropriate space for the abutment.
  • This procedure may be carried out, for example, by inserting a very pointed awl which is inserted between the individual wires and is removed again after pushing apart the litz-wire conductor.
  • a very pointed awl which is inserted between the individual wires and is removed again after pushing apart the litz-wire conductor.
  • a plurality of abutments is also possible which, for example, support each other and may be distributed symmetrically around the litz-wire conductor's central axis.
  • the method according to the invention also includes the positioning of a sleeve around the outer circumference of the exposed litz-wire conductor.
  • the sleeve is preferably positioned in such a way that it surrounds a partial length of the exposed litz-wire conductor and also a partial length of the abutment. That is to say, the sleeve surrounds the exposed litz-wire conductor and the abutment in at least a partial region.
  • the sleeve may be pushed onto the cable in advance before the abutment is inserted into the litz-wire conductor.
  • the reverse process or simultaneous application of the sleeve and introduction of the abutment is also conceivable.
  • the latter particularly if both the sleeve and also the abutment are designed integrally with the contact element (see later).
  • the sleeve is preferably a sleeve with a closed, preferably circular cross-section.
  • the method of the present invention includes firmly bonded joining (compression) of the sleeve to the litz wires and of the litz wires to the abutment as a result of which the contact element is electrically connected to the litz-wire conductor.
  • the contact element may be joined to the sleeve and/or the abutment, in particular it may be formed integrally.
  • the contact element integrally with the sleeve or integrally with the pin.
  • the pin or the sleeve are accordingly separate elements which only enter into a connection with the other elements after the compression.
  • both the sleeve and also the pin integrally with the contact element may be formed from the same material as the contact element, i.e. of copper or alloys thereof or of the same material as the litz-wire conductor.
  • the sleeve and/or the pin of a material different to that of the contact element and/or the litz-wire conductor.
  • the present invention offers the additional advantage that the method can be used for both the contacting of copper cables, i.e. copper litz wires, and also of aluminum cables, i.e. aluminum litz wires.
  • the same contact element geometries and the same method can be used. It may merely be necessary if required to adapt the sleeve diameter to the cross-section which is larger in the case of aluminum than it is with copper.
  • firmly bonded joining is carried out by means of a pressure welding process.
  • An ultrasonic welding process is a possibility here and the sleeve should be centered radially. For this reason and to reduce the process duration, a magnetic pulse welding process is preferred.
  • use of the magnetic pulse welding process also enables high mechanical strengths and uniformly low contact resistances even with large cable cross-sections above 60 mm 2 .
  • the inner side of the sleeve is cold welded to the individual wires which are in contact with it.
  • the abutment substantially centrally into the litz-wire conductor. This can be ensured in such a way that the exposed end of the litz wires is first held completely in a tool which specifies the maximum diameter after insertion of the abutment. Held in this tool, the abutment or a pin for forming a space for the abutment is inserted as has been described above. The pin is centered relative to the tool such that a central arrangement of the abutment relative to the litz-wire conductor can be guaranteed. When using an even number of individual wires, it is possible to arrange the abutment exactly centrally after which the individual wires spread out evenly around the abutment's circumference.
  • the present invention also relates to a prefabricated, single-core or multi-core, shielded or unshielded cable, which for one or a plurality of wires comprises a pin (the abutment described above) arranged in the center of the litz-wire conductor, a sleeve pressed onto the outer circumference of the litz-wire conductor and a contact element, which is joined to the sleeve and/or the pin, is preferably designed integrally and is in electrical contact with the litz-wire conductor.
  • a pin the abutment described above
  • the cable concerned is preferably a round conductor having a longitudinal central axis and the pin is substantially aligned with the longitudinal axis.
  • the individual wires of the litz-wire conductor are formed from aluminum or an aluminum alloy wherein the inner side of the sleeve is cold welded to the individual wires, the individual wires are cold welded among themselves and the individual wires are cold welded to the pin as has been explained above.
  • FIG. 1 a schematic view of a cable having a contact element according to the present invention prior to contacting;
  • FIG. 2 the combination from FIG. 1 in an intermediate step of the method according to the invention.
  • FIG. 3 in schematic form the joining process for the combination from FIG. 1 .
  • FIG. 1 illustrates a cable 1 in schematic form.
  • Cable 1 in the embodiment illustrated is a round conductor having a substantially circular cross-section.
  • Cable 1 has a litz-wire conductor 4 which is formed of individual wires. Unlike as illustrated, litz-wire conductor 4 may be twisted or, as illustrated, may be formed of wires running parallel to each other.
  • cable 1 comprises an insulation 5 in the conventional sense which completely surrounds litz-wire conductor 4 and insulates against outside influences, such as is well known to the person skilled in the art.
  • Cable 1 is stripped at one end of said cable 1 which is illustrated in FIG. 1 . That is to say, litz-wire conductor 4 is exposed over a partial length L. Insulation 5 is no longer present in this area L. If litz wire 4 is twisted, stripping is carried out against the twist in order to align the individual wires substantially parallel to each other at least in end region L which makes subsequent insertion of pin 6 (also abutment) easier, in particular its central introduction.
  • the individual wires of litz-wire conductor 4 are formed of pure aluminum or an aluminum alloy.
  • copper litz wires, magnesium litz wires or litz wires of alloys of these metals can also be used.
  • contact element 2 is formed by contact part 7 , e.g. a cable lug or a round pin (as illustrated).
  • contact part 7 e.g. a cable lug or a round pin (as illustrated).
  • other contact parts i.e. conventional contacts and/or connectors, are also conceivable as contact part 7 .
  • a pin 6 is designed integrally with contact part 7 in the embodiment illustrated.
  • Pin 6 is an elongate abutment whose cross-sectional dimension (in particular diameter) is significantly smaller than the cross-sectional shape of litz-wire conductor 4 (in particular its diameter). If necessary, the cross-section of abutment 6 may correspond to the cross-section of litz-wire conductor 4 . However, larger or smaller cross-sections are conceivable.
  • FIG. 1 shows a sleeve 3 which in cross-section has a closed circular shape.
  • the diameter in this case is slightly larger than the diameter of cable 1 with insulation 5 .
  • the sleeve can only be pushed over litz-wire conductor 4 in region L, but that the diameter is smaller than the diameter of cable 1 in the region of insulation 5 .
  • Sleeve 3 is designed to be thin-walled and preferably has a thickness between 0.1 mm and 0.5 mm.
  • Sleeve 3 is preferably formed of metal, in particular copper or aluminum or an alloy of one of these metals.
  • the sleeve may also have on its surface a metallic coating, such as silver.
  • Pin 6 is formed of metal and preferably has a hardness that is not less than the hardness of the individual wires of litz-wire conductor 4 .
  • a metal in particular copper or aluminum or an alloy of one of these metals, is used.
  • pin 6 may also have a metallic coating, such as silver.
  • the contact part is formed of the same material.
  • cable 1 is first completely stripped in region L. This can be carried out, as mentioned, against the twist of litz-wire conductor 4 .
  • Pin 6 together with contact part 7 is subsequently inserted into the stripped end of cable 1 between the individual wires of litz-wire conductor 4 .
  • litz-wire conductor 4 is divided in the center wherein ideally the individual wires distribute themselves evenly around the circumference of pin 6 .
  • This tool specifies the maximum circumference of litz-wire conductor 4 after division and, with a central introduction of pin 6 , enables the individual wires of litz-wire conductor 4 to yield only in such a way that in the end pin 6 lies centrally in litz-wire conductor 4 .
  • this is only possible if there is an even number of individual wires. With an uneven number, the centrally positioned individual wire of the litz-wire conductor will yield in an arbitrary radial direction. This slight offset to the central arrangement, however, has no significantly negative effect on the joining result and falls within the notion of a central arrangement.
  • pin 6 is substantially aligned with the central axis of cable 1 .
  • the insertion of pin 6 into litz-wire conductor 4 is indicated schematically by arrow A in FIG. 2 .
  • sleeve 3 is pushed over exposed length L of litz-wire conductor 4 or over at least a portion thereof.
  • sleeve 3 completely surrounds one portion of length L of litz-wire conductor 4 and one portion of pin 6 .
  • sleeve 3 is at least arranged such that it surrounds both litz-wire conductor 4 and also pin 6 in a partial region.
  • the sleeve is firmly bonded to litz-wire conductor 4 by means of a magnetic pulse welding process, as disclosed in WO 2008/104668 A1.
  • a current is induced into the sleeve via a magnetic field, said current generating a magnetic field that is directed in the opposite direction to the outer magnetic field.
  • the sleeve is compressed rapidly within microseconds and hits the outer litz wires at high speed. The energy released abruptly on impact breaks open existing oxide layers and leads to cold welding of the metal surfaces.
  • the present invention delivers a method with a short process duration, reliable contact result and flexibility of use.
  • a prefabricated cable is created which has more reliable contacting that in the known prior art and is inexpensive to manufacture.
